Using MIKMIDI library to create a custom Bluetooth MIDI menu experience

[PasqualeTotaro]

Hi Andrew and everybody, this is a question.

I am trying to create an App that connects to Bluetooth MIDI devices without using the default iOS Bluetooth MIDI menu. Why? Because I want to create a more visually pleasing experience for the user and handle automatic reconnection to the device.

The way I am trying to do this is by connecting the device like a normal BLE device and create a MIDI object associated to it. Then whenever the BLE MIDI service updates its characteristic (to send MIDI data) I would use the BLE call back function and stream the data through the MIDI object.

I am using MIKMIDI because it simplifies the whole process, but my question is what MIDI object shall I use?

When I sue the default iOS menu the BLE device appears as a MIDI Device, so my initial thought was to create a MIDI device with driver parameter NULL and connect a MIK MIDI Client to its endpoint to handle the BLE data.

But it fails creating the device (OSStatus -50)

I have also tried to use a MIDI External Device Class, but it has no endpoints to which connect the MIK MIDI Client.

Anybody has a better idea on how to accomplish this?

I also tried to do that, Now I abandon. I found that the system has no api to call to connect MIDI Device
